Browse Forums General Discussion 1 Dec 21, 2018 9:03 pm I live in a house built in the early 80's, meaning that the overall energy efficiency is terrible. As it stands, our AC unit can't keep up with the heat in the 95+ degree days. I'm trying to make some changes to help lower our electricity bill. Here are the facts: 1) Two story home with two car garage on first floor. 2) Master bedroom/bath directly above the garage, kitchen and living room on other side of the two interior walls of garage, none of which are insulated. Exterior wall of garage is brick, unknown if any insulation on that wall behind the drywall. 3) Garage door is a roll up multi-panel door. 4) Garage door faces almost due West, so the sun is hitting on that side of the house during the hottest part of the day, which is usually when the AC starts not being able to keep up. My main question is what type of insulation should I use in the garage door panels? Foam Board? Reflective insulation? Some sort of Batt insulation? I've seen DIY videos suggesting and using all types, but can't seem to find a straight-forward answer of which is most effective against afternoon heat. I want whatever will be the most effective in both summer and the few times it actually gets cold in the winter. What is the minimum R-value I should be looking to achieve? I'll also be re-sealing the garage door to prevent air leaks, but is it also worth it to also insulate the ceiling between the garage and the master bedroom? How about the walls between the garage and the rest of the house? Or is this just overkill? Thanks for any and all advice! new article <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->https://mechanicguides.com/best-4l60e-rebuild-kit/ Re: Insulating Garage Door 3Dec 22, 2018 7:47 am Below is a link to how I insulated my garage door which proved very effective, particularly in keeping the afternoon summer heat out as the door faced west. http://anewhouse.com.au/2015/02/garage-door-insulation/ The Harder You Try - the Luckier You Get !

Re: Insulating Garage Door 4Dec 22, 2018 8:15 am gogo65 Are you in the US? As you are mentioning temperatures in Fahrenheit? In which case product selection will be very different there than in Australia(which is where this forum is based..) I'd guess so, given the use of the term "drywall" rather than plasterboard. I have a vague recollection that R values in NA are not comparable to R values here too, but I have limited knowledge of that. Dover white or surfmist garage door.
